The ham is the star—HoneyBaked or Smithfield are reliable brands for pre-cooked options. Look for spiral-cut to save time (and your knife skills). Most grocery stores carry them year-round now, not just at the holidays. If you’re buying bone-in, ask the butcher to cut it to fit your slow cooker. The glaze ingredients are probably already in your pantry, but double-check the mustard isn’t that old jar from 2019.
No brown sugar? Maple syrup at three-quarters the amount works in a pinch. Swap honey for agave if you’re vegan-adjacent (though this isn’t). Out of Dijon? Regular yellow mustard plus a pinch of cayenne gets you close. The pineapple juice can be replaced with apple juice, but the citrus in pineapple really brightens the flavors. Skip the cloves entirely if you hate the taste (I won’t judge).
Leftover ham keeps 5-7 days in the fridge, wrapped tight. The glaze can be made 2 days ahead—just reheat gently before using. Freeze slices for 2-3 months (perfect for quick weeknight meals). That spiral-cut ham? Even easier to portion for leftovers.

Step-by-Step Instructions for Ham Roast Slow Cooker
This hands-off method delivers a juicy, flavorful centerpiece with minimal effort.
Step 1: Prepare the Ham with Studded Scoring
Start by scoring the surface of the 6 lb bone-in fully cooked ham in a diamond pattern, cutting about ¼-inch deep. This helps the glaze penetrate and creates beautiful presentation. At each intersection, press in one of the 12 pieces whole cloves until they’re securely anchored.
Place the ham flat-side down in your slow cooker. This orientation ensures the meat cooks evenly in the liquid. If your ham is particularly tall, you may need to trim a small slice from the bottom to fit it properly under the lid.
Step 2: Create the Aromatic Cooking Liquid
In a bowl, whisk together the 1 cup pineapple juice, 0.25 cup Dijon mustard, 2 tbsp apple cider vinegar, 1 tsp garlic powder, and 1 tsp onion powder. This tangy-sweet base will infuse the ham with complex flavor as it cooks.
Pour this mixture over the ham in the slow cooker, making sure some liquid pools at the bottom. The acidity from the vinegar and mustard helps balance the sweetness while keeping the meat moist during the long cooking process.
Step 3: Cook Low and Slow to Perfection
Cover and cook on low heat for 5-6 hours or high heat for 3-4 hours. The ham is already fully cooked, so we’re essentially warming it through while allowing the flavors to meld. You’ll know it’s ready when the internal temperature reaches 140°F.
About 30 minutes before serving, carefully transfer the ham to a serving platter. This timing gives you a window to prepare the glaze while the ham rests and firms up slightly for easier slicing.
Step 4: Make the Glaze and Finish
Skim any fat from the cooking liquid and pour 1 cup of it into a saucepan. Add the 1 cup brown sugar, 0.5 cup honey, 0.25 cup orange marmalade, 0.5 tsp ground cloves, 0.5 tsp ground cinnamon, and 0.5 tsp black pepper.
Bring to a boil over medium-high heat, then reduce to a simmer. Cook for 8-10 minutes until the mixture thickens to a syrupy consistency that coats the back of a spoon. Brush this glaze generously over the ham before serving, reserving some to pass at the table.
Pro Tips For Making Ham Roast Recipe Slow Cooker
- Score the Ham: Cut a diamond pattern about 1/4-inch deep into the fat cap before adding the glaze—this helps the brown sugar and honey seep in and creates that sticky, caramelized crust everyone fights over.
- Low and Slow: Set your slow cooker to low for 4-5 hours instead of high; I learned this the hard way after my first ham came out dry and chewy.
- Use a Liner: Line your slow cooker with foil or a slow cooker liner before adding the ham—it makes cleanup a breeze and prevents the brown sugar from burning to the bottom.
- Glaze Last Hour: Mix the brown sugar, honey, Dijon, and vinegar in a bowl, but wait until the last 60 minutes to brush it on, or it’ll just turn into a burnt mess instead of a glossy finish.
Dietary Considerations for ham roast recipe slow cooker
Gluten-Free Friendly
This recipe is naturally gluten-free as written, with all ingredients—from the 6 lb ham to the Dijon mustard—containing no gluten. I always double-check labels at my neighborhood grocery, especially on the orange marmalade, as some brands add thickeners. 💪
Low-Carb Adaptation
For a keto-friendly version, swap the 1 cup brown sugar for 1 cup monk fruit sweetener and reduce the 0.5 cup honey to ¼ cup. The pineapple juice can be replaced with 1 cup low-carb chicken broth to cut additional sugars.
The Dijon mustard and spices remain unchanged, keeping the flavor profile intact while significantly lowering carb count.
Dairy-Free Naturally
No modifications needed—this dish contains no dairy ingredients. The glaze relies on honey and brown sugar for sweetness, while pineapple juice provides moisture. Even the optional orange marmalade is typically dairy-free.
Sodium Considerations
Hams are notoriously high in sodium, so I recommend selecting a low-sodium or no-salt-added variety. Brands like Appleton Farms offer options with 50% less sodium. You can also reduce the Dijon mustard to 2 tbsp to further cut sodium without sacrificing flavor. 💡
Allergen Notes
The primary allergen to watch for is mustard in the Dijon. For those with mustard allergies, substitute with 2 tbsp yellow mustard or omit entirely. The glaze will still be delicious with just the sweet and tangy elements.
Always verify ham labels for soy or egg derivatives, which some processed varieties may contain as binders.

Frequently Asked Questions
Can I use a pre-cooked ham for this?
In fact, the recipe calls for a 6 lb bone-in fully cooked ham. This method simply warms it through while infusing extra flavor. Just ensure it reaches 140°F internally before serving.
What if my slow cooker is too small?
For a 6 lb ham, use at least a 6-quart slow cooker. If yours is smaller, switch to a 4-5 lb ham or cut the larger one to fit. The key is leaving room for the cooking liquid.
How do I prevent the glaze from burning?
Make the glaze separately on the stovetop in 8-10 minutes at medium-high heat. Never add it to the slow cooker directly, as the sugars can caramelize unevenly.
Can I make this ahead of time?
Yes! Cook the ham a day ahead, then reheat individual slices wrapped in foil at 325°F for 10-15 minutes. Reheat the glaze gently on the stove before serving.
